Holy Trinity Church

This small tower across the road from the Houses of Parliament is the only part of the original Palace of Westminster still standing. While it is overshadowed in splendour by the surrounding buildings, it's well worth a visit, and has good displays about the early history of Westminster.

Prestigious contemporary art gallery worth a visit.

The main residence of His Majesty King Charles III, Her Royal Highness Queen Camilla, and latterly of HM Queen Elizabeth II. In the summer, 19 State Rooms are open to the public. Places are strictly limited, and it might not be possible to just turn up and get a ticket for a specific entry time, visitors should book in advance to ensure admission.

A branch of the Imperial War Museum, the Cabinet War Rooms preserves the underground corridors and rooms from which Churchill and the cabinet directed the war against Hitler and the Nazis, maintained almost exactly as they were left in 1945. In 1984, IWM opened the rooms to the public for the first time. In 2005, the attached Churchill Museum was opened as the world's first permanent museum dedicated to the life and wartime achievements of Sir Winston Churchill. Audio guides are included in your admission. No cloakroom, no rucksacks, no suitcases. Café is open daily from 10am to 5pm. Hot food is served until 3pm.

A neoclassical triumphal arch, designed by Decimus Burton and first erected in 1826 as a grand entrance to Buckingham Palace. From 1846 onwards, the arch was topped with a massive equestrian statue of the Duke of Wellington - a major road widening of Piccadilly in 1882 was the opportunity to finally remove the over sized statue to Aldershot. The present magnificent statue Peace Descending on the Quadriga of War was placed on top of the Arch in 1912, and remains today the largest bronze sculpture in the United Kingdom, spectacularly lit at night. During the 1950s, the arch served as the smallest police station in the city, when it was occupied by ten constables, two sergeants and a cat! The arch was opened to the public for the first time in 2001 after a £1.5 million restoration by English Heritage. (Wellington Arch is also available for corporate and private events, with dramatic views down Constitution Hill and across central London from the Arch's spacious balconies, Wellington Arch is a novel and unique place to impress your guests).

The main sights to see in London's Chinatown are the expressions of Chinese culture and Eastern ambience in Chinatown, and for a good Chinese meal. There are few souvenir shops for tourists and no museums or temples. The three ornamental Chinese arches are worth a look. Chinatown does incorporate some entertaining combinations of British and Chinese culture, such as the phone booths with pagoda-style sloping roofs.

Official residence of the Lord Mayor of the City of London, completed in 1753.

In many cities a local transport museum would be of very narrow interest - not London, however! London's public transport is iconic, and the story of how it developed from horse and cart through early buses, Tube trains and trolleybuses to the present day is well worth coming to find out about. There is plenty of opportunity to clamber aboard the historic buses and Tube trains on display. Also, because London's transport is so well known, the museum shop contains plenty of items that make interesting and original gifts and souvenirs.

Historic home to English kings such as Henry VIII, now open to the public. There are many attractions which can occupy a whole day visit, including 60 acres of gardens with the famous maze, the Tudor kitchens, the Chapel Royal, the Great Hall, Mantegna's Triumphs of Caesar paintings, and various exhibitions about Henry VIII.

This enormous arch was built in front of Buckingham Palace. In 1851 the expansion of the palace meant the arch could no longer remain where it was, so it was moved to this point on Hyde Park. It now stands rather sadly on a large traffic island, but the subway beneath the roads means you can stop off at the Marble Arch on your way from Oxford St to Hyde Park.

The Duke and Duchess of Lauderdale's elegant 17th-century manor house, a mile or so upriver from Richmond riverside.

Includes a small but beautiful quad and an interesting Neo-Classical facade. The core buildings of UCL were built after the university's foundation in 1826.

191-m (627-ft) skyscraper can be seen from far away and is the sixth highest building in UK.

The second largest of the London Royal Parks, covering an area of 450 hectares (1,099 acres). Lying north of Hampton Court Palace, the history of the park is inextricably linked to the palace, yet it has always had its own distinct rural character. There are herds of both Red Deer and Fallow Deer, they are wild but usually safe, just don't go too close or get between a hind and its calf. The D-Day linked bits are easiest found from the Teddington side. Go through SHAEF gate and there is an information board. You should be able to spot a flagpole a hundred yards into the park, this marks the spot where General Eisenhower had his office, if you have time, or children who are up for a challenge, there are bronze markers with combined British and Canadian and US flags at the corners where the main buildings of Camp Griffiss were. The partially restored early 18th-century baroque water gardens are a short walk from the Hampton Hill gate. The park is subdivided by Chestnut Avenue, Christopher Wren's grand approach to Hampton Court Palace which runs from Teddington Gate to Hampton Court Gate and with the gilded Diana fountain closer to the Palace end (you may have seen it as location for the finish line of some of the cycling events at the 2012 Olympics).
